I just was on the phone with my power provider at home. My rate 25 cents just jumped to 33 cent p KWH. A 32% jump! I would swear a contract signed in September 2016 for .25 would last a bit longer!!
I doubt Flow Batteries want lithium to fail. I did think the comment "Flow batteries are experimental" in the article was a little suspect. It has been used for decades since 1970s in various forms and even well before that.
33cents- wow!!!! Feed in rate 7cents. Batteries looking so close for home as well!
